Abstract

" PROCESSO PARA PRODUZIR UMA CONEXãO ROSCADA DEFINIDA " A invenção trata de m processo de produzir conexões roscadas específicas, dois componentes sendo compelidos um contra o outro, com protensão predeterminada por intermédio de um parafuso que é girado por um dospositivo de aparafusar que pode ser regulado , e o parafuso produzindo uma emissão acústica. A invenção é caracterizadas pelas seguintes etapas: detecção da emissão acústica que é gerada no parafuso durante um processo de aparafusar efetivo; e comparação da emissão acústica detectada ocorrendo durante o processo de aparafusar efetivo com dados armazenados predeterminados, sendo determinado de acordo com critérios predeterminados se o parafuso de aparafusar está se processando corretamente. O processo de preferência pode ser usado em processos de montagem na produção industrial."PROCESS TO PRODUCE A DEFINED THREADED CONNECTION" The invention deals with a process of producing specific threaded connections, two components being forced against each other, with predetermined prestressing by means of a screw that is rotated by a screwing device that can be adjusted , and the screw producing an acoustic emission. The invention is characterized by the following steps: detection of the acoustic emission that is generated in the screw during an effective screwing process; and comparison of the detected acoustic emission occurring during the actual screwing process with predetermined stored data, being determined according to predetermined criteria if the screw is being processed correctly. The preferred process can be used in assembly processes in industrial production.
